论"精确处方"与"模糊处方"

药物与药物合用之后可能发生的关系,称为"药际关系",这种关系是客观存在,而配伍则具有主观性。要使配伍的主观愿望得以实现,必须使药物符合"好的药际关系"。经方、时方产生的根源正在于是否符合"特别好的药际关系"。在此基础上,可由含糊的经方、时方的概念,推出"精确处方"与"模糊处方"的新概念。由此,方剂大致可区分为两大类,这样的区分,使方剂学教学和方剂学研究今后可以向着两个不同的方向发展,而临床运用方剂也可以按不同的思路进行。

Assessment of Anti-Quorum Sensing Activity for Some Ornamental and Medicinal Plants Native to Egypt

This study investigated the effects of some plant extracts on the bacterial communication system, expressed as quorum sensing (QS) activity. Quorum sensing has a directly proportional effect on the amount of certain compounds, such as pigments, produced by the bacteria. Alcohol extracts of 23 ornamental and medicinal plants were tested for anti-QS activity by the Chromobacterium violaceum assay using the agar cup diffusion method. The screening revealed the anti-QS activity of six plants; namely the leaves of Adhatoda vasica Nees, Bauhinia purpurea L., Lantana camara L., Myoporum laetum G. Forst.; the fruits of Piper longum L.; and the aerial parts of Taraxacum officinale F.H. Wigg.     

In vitro antiproliferative characteristics of flavonoids and diazepam on SNU-C4 colorectal adenocarcinoma cells

The need for beneficial use of sedatives in oncologic patients is increasing. Therefore, in this study, antiproliferative characteristics of herbal and synthetic sedatives were examined in vitro in SNU-C4 human colorectal adenocarcinoma cells. Apigenin (50% inhibition concentration, IC₅₀ = 1.8 ± 0.5 μM) and diazepam (IC₅₀ = 7.0 ± 0.5 μM) showed concentration-dependent inhibition of SNU-C4 cancer cell survival. Efficacy of cancer cell survival inhibition by apigenin and diazepam was much lower than that of 5-fluorouracil (5-FU), a known chemotherapeutic drug. However, 10⁻⁶ M concentration of apigenin and diazepam potentiated 5-FU-induced cytotoxicity. In SNU-C4 cells, 10⁻⁶ M concentrations of diazepam, flumazenil (Ro15-1788), Ro5-4864, or PK11195, all ligands for central- or peripheral-type benzodiazepine (BZD) receptors, inhibited cell survival like the flavonoid apigenin (4′,5,7-trihydroxyflavone) and fisetin (3,7,3′,4′-tetrahydroxyflavone). Also like the plant flavonoids, treatment with 10⁻⁶ M concentration of diazepam for 3 days hardly affect the peripheral-type BZD receptor (PBR) messenger RNA (mRNA) expression and inhibited glucose utilization of SNU-C4 cells. Treatment with flavonoids or diazepam for 6 days upregulated PBR mRNA expression and cell cytotoxicity of SNU-C4 cells. Furthermore, treatment with 10⁻⁶ M concentration of apigenin, a natural sedative material originating from traditional herbs, positively modulated BZD-induced antiproliferative cytotoxicity in SNU-C4 cells. Overall, the in vitro antiproliferative activity on SNU-C4 cancer cells of herbal sedatives, such as apigenin, plus additive enhancement of synthetic BZD- and 5-FU-induced antiproliferative activities, were shown. In conclusion, this study provides experimental basis for advanced trial in the future.
